Application filed February 10, 1908. Serial No. 415,145.

To all whom it may concern:

Be it known that we, OWEN DODGE and SAMUEL G. CAMP, citizens of theUnited States, residing at Colorado Springs, in the county of El Paso,State of Colorado, have invented a new and useful Chandelier, of whichthe following is a specification.

This invention has reference to iinprovements in chandeliers, and isdesigned to provide a combined electric and gas chandelier, with the gaschandelier having a fixed elevation and the electrolier being adjustableas regards its height above the floor.

The present invention is in part an irnproveinent over an adjustablechandelier for which application in the naine of inyself and SaniuelCamp was niade for Letters-Patent on April 10, 1907, Serial No. 367,387.

The chandelier of the aforesaid application was designed as anelectrolier only and einbodies means whereby certain portions of theelectrolier are readily adjustable to various heights above the floor.The saine features in the inain are retained in the chandelier of thepresent invention, but certain modifications are inade in the structureand the chandelier is further inodiiied so as to be used in connectionwith gas lights in order that either or both kinds of illuininationsniay be used, as inay be desired, or as the eXigencies of the case niaydeniand.

In accordance with the present invention there is provided a chandelierthrough which there are gas passages connected with the gas mains andwith which gas passages 'suitable gas brackets may be connected so as tosupply the gas jets with gas without interference with other parts. Thegas 'fixtures are not adjustable with relation to the floor, andconibined with these non-adjustable parts are electrical iixtures whichmay also be non-adjustable, but which inay be used without interferencewith the gas fixture side of the structure. Connected with the gas pipesbut without interfering with the functions thereof, is an adjustablemember carrying electric fixtures and similar to the like parts shown inthe application before inentioned.

The invention will be best understood by reference to the followingdetail description taken in connection with the accompanying drawingsforming part of this application, in which drawings- Figure 1 is alongitudinal section, partly broken away, of the improved chandelier.Fig. 2 is a side elevation of a cam ineniber shown in Fig. 1. Fig. 3 isa detail view of a means of locking the niovable parts of the structurein place. Fig. 4 is a central cross section through the lower end of thegas portion of the chandelier, Fig. 5 is a section on the line y-y ofFig. 1 but oinitt-ing certain parts. Fig. 6 is a central, longitudinalview of another forni of the invention, with parts in elevation, andFig. 7 is a section on the line z-z of Fig. 6.

Referring to the drawings, there is indicated a ceiling 1 which is shownin a purely conventional inanner, and from this ceiling there isindicated the 'fixed end 2 of the usual gas pipe. Secured upon this pipeis an insulated connection 3 of a common or corninercial forni used inthe installation of gas and electric fixtures but forms no part of thepresent invention and need not be particularly described.

Screwed into the insulator is the neck 4 of a block 5, which latter maybe of cylindrical shape and has an entering passage 6 extending throughthe neck and then dividing into two other passages 7 leading to theouter walls of' the block. Between the passages 6, 7 is a centrallongitudinal passage 8 formed in the block, and this has a lateralextension 9 leading to the walls of the block but having no connectionwith the passages 6 and 7. The passage 8 is counterbored and adapted toreceive the neck 10 of another block 11 `through which is a centralpassage 12 in line with the passage S. Exterior to the block 5 is theupper end `of a pipe 13 of suitable length, secured thereto and carryingat its lower end a support 14 from which project lateral arms 15connected Aby annular webs 16. The arms 15 have passages 17 terminatingin threaded sockets 18 for the reception of suitable gas jet arnis, asshown in the drawings or which may be of the ordinary type used in gaschandeliers.

The block 11 carries the upper end of another pipe 19 which in turn isconnected near its lower end to the lower end of the support 14, andthese pipes 13 and 19 are so connected at their two ends as to forni agas tight annular passage between thein and into the passages 17. Thusthc gas pipe 2 is connected through the insulating coupling 3 to thepassages 6 and 7 and by way of the annular passage between the pipes 13and 19 to the gas pipes screwed into the sockets 18. EX- terior to theIpipe 1,3;and secured at its lower' end to the support 14, and spacedfrom the pipe 13 by an annular flange 2O formed on the support 14, isstill another pipe 21 which eonstitutes the exterior member of thechandelier and may be of; any ornamental design desired. The upper endof this pipe may abut against the coupling 3 and may be surrounded by asuitable rosette 22 for ornamental purposes.

The webs 16 are each provided Aat diametrically opposite points withscrew sockets 23r into which may be inserted electrolier arms' of usuallconstruction, andA current is carried to these armsthrough conductors 24which are carried up through suitable recesses 25 in the sides of thesupport 14 exterior to the pipe 13 and between the same and the outerpipe 21 to a point ofentrance for the electric conductors adjacent tothe passage 9 before referred to, which passage may be coincident withsuitable openings, not shown, which may be considered as present in thepipes 13 and 21. vWithin the pipe 19 there is still' another pipe 26,and interior to this last-named pipe is another pipe 27'. The pipe 26may have formed at its lower endA an annular flange 28 which is ofsuchsizevto guide without binding the pipe 27'. The upperend of the pipe27 receives a nut 29, and if need be a clamp nut 30.- Belowthe nut 29 isa washer 31, and below the washer the pipe is` surroundedv by an elasticring 32 resting on another washer 33 against which abuts the upper endof the pipe 26. The lower end ofthe pipe 27 has secured to it a sleeve34 formed at its lower end with a socket 35 and at its upper endreceiving a washer 36'. y

Surrounding the pipe 27 between the washer 36A andthe flange 28 is ahollow cam member 37y having two parallel surfaces 38, 39', which, whenthe bore 40 of the hollow cam member is concentric with the pipe 27,areat an angle to the longitudinal axis of the pipe. rIhe cam member hasstill another surface 41, and the distance between the surface 41' andthe lower-corner 42v of the cam member is greater than the distancebetween the surfaces 38 andi39 sothat when the cam member is so turnedvby means of a manipulating handle or thumb piece 43 as to bring thesurface 38 parallel with the flange 28, and the surface 39 parallel withthe washer 36 the washer 36 and the flange 28 are brought intocloser-relation than when the cam member is turned to bring the surface41 into engagementl with the flange 28 andthe edge 42 into engagementwith the washer 36. The two pipes'26 and 27 are movable longitudinallywith reference to each other by means of the cam member, but when thecam member is so manipulated as to increase the distance between theflange 28 and washer 36 the washer 31 is brought into closer relationwith. the washer 33 and consequently the elastic sleeve 32 is`compressed and expanded laterally until it is brought into such firmrelation with the pipe 19 as to firmly hold the pipes 26 and 27 in anyadjusted position with relation to the pipe 19. This provides a meanswhereby the pipes 26 and 27 may be adjusted to any point desired withrelation to the floor. r1`he socket 35 is provided for the purpose ofreceiving an electric fixture ofI any desired type, andv current isconveyed to this fixture through a conducting cord 44 e);n tendingupward through the pipe 27, thence through the passages 1-2 and 8 intothe passage 9, and so to the feeding line. 1n order that the pipes 26and 27 may be extended below the gas member of the chandelier, aconsiderable excess length of the conductor 44 is coiled within thespace above the pipe 27 within the pipe 19, as indicated at 45.

in Fig. 6, there is shown a different means for mounting and clampingthe tube 26 than that shown in Fig. 1. The lower end of the tube 19 issplit longitudinally for a short distance as shown at 45, and betweenthe split lower end of the tube 19 and the outer wall of` the tube 26the ring' 32 is located. Surrounding the split Lower end of the tube 19is a split clamp ring 46 having its ends terminating in two opposedparallel wings 47. Hinged to these wings 47 and straddling the same isthe forked end 48 of a thumb lever 49. The hinge joint is formed by athrough pin 50. lThe two legs of the fork of the lever 49 are made toapproach each other at right angles to the length of the lever so thatwhen the lever is in one position, say the horizontal position, thewidest portion of the forked end 48 is coincident with the two wings 47,and the clamp, which is made elastic, springs outward thus releasing thelower end of the tube 19 from pressure and thereby allowing the ring 32to expand and release the tube 26 to longitudinal movement. When thelever 49 is moved downward toward the tube 26, the contracted portion ofthe forked end 48 engages the wings 47 and forces them together, thusclamping the ring 46 upon the tube 19 and through it forcing the ring 32into closev engagement with the tube 26 and thereby holding it firmly.The upper end of the tube 26 is swaged so as to be expanded sufficientlyto snugly but not tightly fit tne interior of the tube 19, thus servingto guide the upper end of the tube 26 in its travel along the tube 19.lin Fig. 6 the and electric connections have been omitted but will, inpractice, be the same as in the structure of Fig. 1.

lt is thus apparent that with the improved structure not only may we beenabled to provide the drop electric light witha wide range of movementand safely anchored at any adjusted position, but we are enabled to usethe chandelier for the ord-inary purposesof a gas chandelier, and inaddition thereto for the ordinary purposes of an electrolier without anyinterference of one with the other in any respect. Furthermore, theclamping mechanism for locking the adjustable parts in position in nomanner interferes with the use of the electric light fixtures andenables us to carry an electric light iixture on the lower end of theadjustable part of the chandelier without affecting the relation of thiselectric light iixture to the adjustable part of the chandelier when theadjustments are made.

While we have described particular cam structures we are by no meanslimited to these particular structures but may use other forms of camsfor eilecting the locking of the movable member of the chandelier. As tothe material of the elastic ring 32, this of course will include variousknown elastic materials such as rubber, or leather, or expansiblemetallic rings may be used in this construction.

Vhat is claimed is 1. A chandelier having two concentric spaced tubesarranged to provide a gas passage between them, which passage leads froma source of supply to gas jets, a longitudinally adjustable memberinterior to the inner of the two tubes for carrying electric lightlixtures and adapted to receive electric conductors housed in said innertube, an outer tube exterior and in fixed relation to the gas conveyingtubes and spaced therefrom and adapted to receive electric conductors inthe space thereby inclosed, a block connecting the upper ends of saidgas conveying tubes and having a passage to receive gas and to directthe same to the space between said tubes, the outer one oi the two tubesforming the closure for the outer ends of the gas passages in saidblock, the block being also provided with another separate passageadapted to receive an electric conductor leading to the longitudinallyadjustable member.

A combined electric and gas chandelier comprising a number oi concentricspaced tubes or pipes, a block connecting the upper ends of two adjacenttubes and having passages therethrough for conveying gas to the spacebetween the tubes and also having another passage interior to thegas-conveying space for the reception of an electric conductor, a gasiixture support at the lower ends of the gas-conveying tubes, said gasiixture support being provided with means for supporting electricfixtures, electric conductors leading through the space between the gastubes and a tube exterior thereto and adapted to supply current to theelectric hxtures carried by the support at the lower ends of the gastubes, and another longitudinally-adjustable set of tubes movableinterior to the gas tubes and receiving the conductor entering throughthe said block, said adjustable tubes being provided with means forreceiving electric fixtures and with means for locking the tubes in anyposition of adjustment.

3. In a chandelier, a number of concentric tubes arranged for thepassage of gas and electric conductors, one set of tubes beingadjustable longitudinally with relation to the gas tubes, and a clampingmeans for locking the adjustable tubes in any position of adjustmentcomprising a laterally-expansible sleeve carried by the adjustable tubesand arranged to engage the inner walls of one of the gas tubes, and acam mounted loosely on and surroiuiding one of the adjustable tubes andacting to move the tubes longitudinally with relation one to the otherto cause the expansion of the locking sleeve.

Ll. ln a combined gas and electric chandelier, a number of concentrictubular members for the passage of gas and for the housing of electricconductors and a supporting block for the tubular members having acentral passage through a portion of its length and diverging for theremainder of the length thereof, and terminating at the outer wall ofthe block, the outer member of the gas conveying tubular members formingthe outer wall of the diverging branches of the gas conveying passagethrough the block, said block being formed with another passageindependent o the gas passage and leading to the interior of theinnermost tube of the gas passage.

5. A chandelier having parts longitudinally ad'ustable and comprising arelatively iixed tube, two other tubes one within the other and having alimited relative movement one to the other and housed in the iirst-namedtube, a laterally-expansible member compressible by longitudinalmovement of the two tubes that are relatively movable one to the other,and means for effecting the longitudinal movements of the tworelatively-movable tubes comprising a cam member loosely surrounding thesma!ler of the tubes, said cam member having flat engaging facesarranged at an angle one to the other and perpendicular to diameters ofdifferent lengths.

In testimony that we claim the foregoing as our own, we have hertoaiiixed our signatures in the presence of two witnesses.
